Flip Particle System Graph

Hi all,

I was wondering if anyone knew of a way to flip graphs on a particle system? I don't think it's available out of the box, but does anyone have any idea on how I might be able to achieve this through some script or any other means?

I uploaded two pics below on what I mean. It's easy to do manually for simple graphs, but was wondering if there was a way to just maybe right click on the graph and do something like a flip-vertical or flip-horizontal and get the graph with all its vertices to flip.

Thanks for any help on this!
